I've been using Termux over SSH for quite a while now. I've always done so over WiFi. This works reasonably well at home, where I controll the IP Addresses. In other networks it was more annoying, because I always had to run ifconfig first, to get my IP. But the big annoyances start when you want to use it in a place that has no WiFi network available. Previously, I used an Android tablet and a keyboard. With this I set up a WiFi direct connection between my phone. It's wonky and sometimes requires to restart both devices before working again, but it works.

Tinier is a pretty cool font. It is a so called pixel font, and it is just about the smallest font I could find. The letters can be displayed at a font-size of 4px. This means that each character is only 3 pixels tall.

I managed to build a bridge between Termux and Minimalistic Text using Tasker. I use it to display the last 20 lines of the #termux irc channel as you can see in the picture.
I've done it without having Tasker check a file every two minutes. The Task is directly called from the script.
